Abstract (en)
[origin: US2019139602A1] A method of reading a memory device having a plurality of memory cells by, and a device configured for, reading a first memory cell of the plurality of memory cells to generate a first read current, reading a second memory cell of the plurality of memory cells to generate a second read current, applying a first offset value to the second read current, and then combining the first and second read currents to form a third read current, and then determining a program state using the third read current. Alternately, a first voltage is generated from the first read current, a second voltage is generated from the second read current, whereby the offset value is applied to the second voltage, wherein the first and second voltages are combined to form a third voltage, and then the program state is determined using the third voltage.
